Abstract (en)
[origin: EP2602300A1] Provided is a photochromic composition which can function as an adhesive layer for bonding optical sheets made from a polycarbonate resin or the like and which can yield a laminate that exhibits excellent tight adhesion, heat resistance and photochromic properties. The photochromic composition is, for example, a composition which comprises: a polyurethane-urea resin (component (A)) obtained by reacting a polyol compound (component (A1)), a polyisocyante compound (component (A2)) that has two or more isocyanato groups in the molecule, and an amino-containing compound (component (A3)) that contains two or more isocyanato-reactive groups in the molecule, with at least one of the isocyanato-reactive groups being an amino group; and a photochromic compound (component (B)). The amino-containing compound (component (A3)) is a diamine or the like.
